COAL-STOVE.

The Scue difle referred to in these Letters Patent. and making part of the same.

Be it" known that I, WA'rsON SANFORD, of the city, county, and State of New York, have invented certain new and nsefullmprovements in Stoves; and Ido hereby declare, the following to be a full, clear,'and

enact description thereof, reference being bad; to the accompanying drawings, and to the figures and letters marked thereona the stove between the fire-pot and body, consistingof a series of openings placed therein. v Second, in an improvedcombination and arrangementof the firc-potand body, and contracted neck,

either with or withoutaseries of openings.

To enable those skilled in the art to construct and use my improvements, 1 will proceed to describe the same. a I

v a is the fire-pot; b is a rim, extending inward, and

i to some extent, over such fire-pot, and may be either convex or flat.

' The rim or ring so constructed causes the gases to reverberate, and to throw themselves back again on ,to the fire, consuming them more or less, and thereby causing greater heat and economy of 'fuel. Thus,

in such hemispherical fire-pot, the heat is compressed, retained, and revel-berated, and is thereby intensified, whereas in the old straight pot, the gases are permitted to pass 05', unretarded, to the chimney.

At the point of greatest contraction of this rim 1), is a flange, c, which can. be corrugated or perforated, shown as corrugated .in the drawings, and thus permit of the introduction of oxygen to .mix with the products of combustion, and. insurea more perfect combustion by more thoroughly igniting them, and thereby producing a still further economy of fuel.

Above this contracted neck is the body, d, of the stove, constructed in an almost inverted form to the fire-pot, before described, as fully appears by the drawings, thus causing a second reverberation of the prodnctsof combustion, retaining them, longer, and

more thoroughly utilizing their component parts.

WhatI claim as new, and desire to secure by Letters Patent, is-

1. The arrangement of aserics of openings in the neck, and between the fire-pot and the body of the stove, substantially as described.

2. The combination and arrangement of the body and fire-pot with the 'neck, with or without a series g of openings, substantially as described.
